• Levels of Ki67+ expression by CD8+ T cells and NK cells increased by 17-fold and 10-fold, respectively, in the third cohort (30 μg/kg dose) when compared to baseline
• NK cell / Treg and CD8+T cell / Treg ratios increased by 4.4-fold and 2.6 fold, respectively, at the 30 μg/kg dose, demonstrating superior stimulation of cancer fighting immune cells.
• Significant dose-dependent increases in CD8+ T (>3-fold) and NK (>6-fold) cells indicates potential for further expansion of anti-tumor immune cells as dose-escalation continues
